This'invention relates to improvements in hinges and more particularlyto'hinges of the type in which the hinge pin is entirely concealed whenthe hinge is assembled. 'The hinge is particularly adapted for use onrefrigerator doors although, obviously, hinges embodying the essentialsof this invention have various uses. I

A particular object of the invention'isto provide a hinge which maybereadily formed from sheet metal by the so-called stamping process andwhich will have a hinge pin arranged so that it will be entirelyconcealed when the hinge is assembled and yet held 1 firmly in operativeposition but which may be removed if desired to disassemble the hinge. Aspecific feature of the invention resides in the particular sheet metalconstruction of the hinge by means-of which the concealed pinconstruction is effected. Although the drawings and followingdescription discloses a hinge of sheet metal construction the essentialsof the invention pertaining to the concealed'hinge are applicable toother hinge structures, The invention provides various new and usefulfeatures ofconstruction and arrangement as hereinafter more fullydescribed and pointed out in the claims,

reference being had to the accompanying drawings in which, a

Like reference characters refer to like parts inthe diiferent figures ofthe drawings.

The hinge comprises what may be termed afi'xed plate 1 and a swingingplate 2, each of which may be readily stamped "from sheet metaland-"each being provided with the-customary screw holes 3 to receivescrews by which it may be attachedto the jamb and door respectively. Thefixed plate 1 is pro vided with outwardly extending ears 4 formedintegrally of the sheet metal of the plate, which ears are closed ontheir outer sides'and open on their inner faces. The ears and theundersideo'f the base form receptacles to receive the hinge pin holdingmember 5, which is substantially'a U-shaped member having upwardlyextending legs 6 at its respective ends, said legs being of channelshape and having open bosses 7 provided at each upper end. The legs 6 ofthe member 5 are inserted from the underside of the hinge member andextend into the ears 4, preferably being madeto fit tightly therein. Thelower portion of the member 5 is arranged substantially flush with thelower portion of the hinge member 1 so that when this'hinge member isattached to the door jamb the member 5 is retained in operative positionin the member 1 and the abutting of the member 5 also strengthens thehinge mounting structure.

The swinging hinge member 2,also readily stamped from sheet metal, hasan extension 8 arranged to extend between the ears 4 and this extension-8 is providedwith a apart points 12 through a position of itscircumfere-nce. I

The hinge pin is formed of two members 13 which are located within thesleeve 9 and their combined length is no greater than the total lengthof the sleeve. These hinge pin members 13 are mounted for longitudinalmovement in the sleeve and may be moved by inserting an instrumentthrough the slot 10 in the sleeve, the said slot 10 being accessiblethrough the open inner and underside of the hinge member 2.

In assembling the hinge, it being understood thatthe hinge pin holdingmember 5 has been arranged in place in the fixed hinge member 1, thehinge pin members 13 are re tracted into the sleeve 9 as shown in Fig. 5placed into position and the extension 8 is between the ears 4 and thelegs 6 of the member 5 which are located within the ears and areprovided with the open bosses 7 WVhen the extension 8 is in its properposition a small instrument is inserted into the slot 10 of the sleeve 9and by engaging the inner ends of the pin members 13 they may be,

" moved outwardly and inserted-into the respective hollow bosses 7 andwhen in this ex tended position the tongue 11 is bent inwardly betweenthe inner ends of the pin members 13 preventing them from inadvertentlyre-,

tracting into the sleeve 9; -'See' Figs. 3

" provided for that 7 and is rigid and durable.

and 4. r .With the parts in the above described po-. sition therespective pin members13 effectively provide axes members on which themembers 1 and 2 of the hinge pivot and the pin members are entirelyconcealed at the outside of the hinge. able.to disassemble the hinge thetongue 11 may be bent outwardlyby an instrument purpose so that the pinmembers 13 may again be retracted into the sleeve 9 to permit 8 frombetween the ears 4.

' The hinge pin embodying this invention as I above described hasvarious'advantages. It

provides, in the first place, a hinge of ex tremely attractiveappearance because of the absence of the projecting or visible ends ofthe hinge pin and this construction permits, the ears 4 to be smoothlyfinished. When a hinge is chromium'plated its parts must be platedseparately before being assembled and it would be impossible to platethe ordinary hinge pin and then rivet its ends to hold it in placebecause this riveting operation would ruin the chromium plate but withthe present hinge the exposed parts may be properly plated may becromium plated if desired because no riveting or operation detrimentalto the plating is used but inasmuch as thepin' is not visible it is notnecessary to plate it. Furthermore, the hinge-is simple to'construct Ifit should be desire removal of the extension,

and the hinge pin The foregoing description and the drawings disclose ahinge of sheet metal construction but it is conceived within the scopeof this invention that the same type of con cealed hinge pin may beapplied to other forms of construction.

The hinge members 1 and 2 could be of cast metal with the sheet metalsleeve 9 inserted with its bendable tongue to carry and hold the pinmembers extended or a spacing member of a different type than the tongue11 might be substituted to be inserted between the inner ends oftheextended pin members 13 to hold them extended and in operativeposition. 3

While we have described a complete embodiment of our invention we do notwish to be limited to the particular construction shown, our inventionbeing in fact limited solely by the attached claims.

We claim: r

1. In a hinge, a hinge plate having spaced apart ears, each ear havingahinge pin re-- said extension and extendible into the open ings of therespective ears and a flexible tongue forming a part of the saidextension structure bendable into a position between the inner ends ofsaid hinge pins to retain them in extended-position.

2. In a hinge, a hinge plate having spaced apart ears, each ear having ahinge pin receiving opening, a second hinge plate having anextensionbetween said ears, a sleeve fixed in said extension, two hinge pinsmounted for longitudinal movement in said sleeve and extendible into theopenings of the respective ears and a flexible tongue formed on saidsleeve and bendable into a position between the inner ends of said hingepins to retain them in extended position.

3. In a hinge, a hinge plate having spaced apart ears, each ear having ahinge pin receiving opening, a second hinge pin having an extensionbetween said ears, a sleeve fixed in said extension, said sleeve beingprovided with a substantially centrally located opening, two hinge pinsmounted for longitudinal movement in said sleeve and extendible into theopenings of the respective ears, and a tongue formed on said sleeveadjacent said opening therein and bendable into a position between theinner ends of said pins to retain them in extended position.

4. In ahinge, a hinge plate having spaced apart hollow cars, a hingepinsupporting member having two legs each insertable in the opening of arespective ear and .each leg having a hinge pin receiving opening, asecond hinge plate having an extension located between said ears and therespective legs of the hinge pin supporting member tures.
